If you have the right ingredients you could make your own. Here are addresses to three different recipes you could try: 1. http://www.recipetips.com/recipe-cards/t--121619/easy-pizza-sauce-3.asp , 2. http://www.recipetips.com/recipe-cards/t--121206/pizza-sauce-9.asp , 3. http://www.recipetips.com/recipe-cards/t--124919/pizza-sauce-13.asp . Other than making homemade sauce, there is not another product that I would suggest substituting for pizza sauce.
